lift [%PREMIUM_LINK%] (lĭft) Pronunciation Key |
An upward force acting on an object. Lift can be produced in many ways; for example, by creating a low-pressure area above an object, such an airplane wing or other airfoil that is moving through the air, or by lowering the overall density of an object relative to the air around it, as with a hot air balloon. Compare drag. See also airfoil, buoyancy. See Note at aerodynamics.
